I think that group, at least the black guy (don’t know his name) and woman, that Rick kicked out of the prison when he was in his really crazy stage, are going to team up with Andrea and go back to Rick’s side. Maybe more will follow. And I’m hoping Morgan shows up with his truck load of weaponry, too.
Tyreese and his sister Sasha. I wonder if they are the Woodbury dissenters hinted at in the spoilers?
